Microsoft has unveiled the second platform preview for IE10, unveiling better support for HTML5 and new security features.Internet Explorer 9 only came out in March, and IE10 is still in the early stages of development. Microsoft is releasing so-called "platform previews", which show the latest additions to the browser's engine without any of the user interface laid on top, as it did with IE9.
The second platform preview includes HTML5-based drag and drop to move files, support for HTML5 forms, and CSS3 positioned floats, which will allow text to flow around images on the screen.
Improvements to parsing behaviour will mean developers can write code once and have it work the same across all browsers, according to Microsoft. Ryan Gavin, senior director of Internet Explorer business and marketing, said Microsoft was working on "very deep HTML5 support with an ear toward interoperability and a vision we call 'same markup' where the developer can write the code once and have it work across browsers and work across the web".
IE10 will also feature a new sandboxing tool, which prevents third-party elements, such as maps, from accessing the rest of the data on a page.
